Characteristics Of The Eastern Adriatic Current In The Coastal Area Between Dubrovnik And Bar

The research of sea currents in the Adriatic has a long history. Numerous methods of current measurements as well as indirect methods of current determination were applied. A large number of numerical models were developed to explore variability of the Adriatic current system at various space and time scales. Direct long-term measurement of the sea currents in front of Dubrovnik in combination with the Princeton Ocean Model (POM) adapted for the whole Adriatic were used in this paper to describe a part of very stable Eastern Adriatic Current (EAC) in the coastal area between Dubrovnik and Bar where the coastline is generally oriented in the direction of NW-SE, without larger islands. It was found that at the current meter station with total depth of over 100 m off Dubrovnik, the current directions were dominantly between WNW and NW with very high stability factor, while the most intensive currents were recorded in WNW direction, parallel with the coastline. The maximum current flow near the surface was about 95 cm/s, while at the bottom it was weaker, about 40 cm/s. Intensity and stability of the East Adriatic Current flow in the area between Dubrovnik and Bar, as well as the existence of South Adriatic Cyclonic Gyre over the southern Adriatic Pit were confirmed also by the POM model results. Obtained results imply that all waste that reaches the sea in the coastal area southeast of Dubrovnik will likely pollute the whole area towards northwest.
